Many people like to use body weight as a motivating factor to stay focused on their fitness goals. Beware of getting caught in the number trap.
Weight is important, but please don’t let it be your success or failure mark. Many things change throughout the month, and as your body cycles (both men and women) your body weight will change. This is true during the day as well, you will weigh different in the morning than the evening. Your body weight may fluctuate around 5lbs in a day – so how can that be a great indicator? Plain and simple it isn’t.
If you must weigh yourself, do so on the same day of the month and at the same time each weigh-in. It is easiest to do this when you wake up, you’ll be able to wear the same thing and generally have eaten the same thing prior to weighing – nothing for approximately 8 hours. You can weigh yourself in between your monthly weigh-in but I caution you to not be too tied to that number instead use it to keep you focused on working out.
Finally, remember a weight measurement in fitness is a time measurement. To get the most accurate idea of how you are doing you must track this measurement over a period of time.
